Dc motors basics
DC motor is majorly comprised of two parts, Stator (static part: permanent magnet) and Rotor (rotating part: armature winding). The armature is placed in the magnetic field produced by the north and south poles of a permanent magnet as shown in Fig.3 (a), (b). See more Where, Ia(t) represents the armature current, Lais armature winding inductance, Ra is the armature winding resistance, and Ea(t) is the back-emf … See more Where, kb is the back-emf constant. Additionally, the motor generates a torque Te(t) proportional to the armature current, given as; See more Where, kT is the torque constant. When a DC motor with the output torque in Eq. (3) is driving a mechanical load system, the rotor speed can be determined from the equation of motion; See more WebOct 25, 2024 · DC motors like this are great for battery-powered toys (things like model trains, radio-controlled cars, or electric shavers), but you don't find them in many household appliances.
